On the optimality of multiantenna broadcast scheduling using zero-forcing beamforming
Abstract--Although the capacity of multiple-input/multipleoutput (MIMO) broadcast channels (BCs) can be achieved by dirty paper coding (DPC), it is difficult to implement in practi...

Power Optimal Scheduling for Guaranteed Throughput in Multi-access Fading Channels
Abstract— A power optimal scheduling algorithm that guarantees desired throughput and bounded delay to each user is developed for fading multi-access multi-band channels that can...

Secure Broadcasting
Abstract—We study a problem of broadcasting confidential messages to multiple receivers under an information-theoretic secrecy constraint. Two scenarios are considered: 1) all r...

Power and Bandwidth Allocation in Cooperative Dirty Paper Coding
—The cooperative dirty paper coding (DPC) rate region is investigated in a two-transmitter two-receiver network with full channel state information available at all terminals. Th...

Network Coding for Two-Way Relay Channels using Lattices
—In this paper, we propose a network coding using a lattice for the two-way relay channel with two nodes communicating bidirectionally through a relay, which we call modulo-andfo...
